弁。 The valve body is provided with an outer temperature chamber and an inner low-pressure refrigerant chamber separated by a diaphragm, and a connection port for the evaporator outlet side and a connection port for the compressor inlet side are provided at both ends of the low-pressure refrigerant passage communicating with the low-pressure refrigerant chamber. A connection port for the inlet side of the evaporator and a connection port for the outlet side of the condenser are formed at both ends of the passageway, which has a valve seat for the expansion orifice in the middle, and a valve body for opening and closing the valve seat is provided with a spring. A temperature sensing tube is connected to the temperature chamber to detect the degree of superheat, and the diaphragm is displaced based on the degree of superheat captured by the temperature sensing tube. An expansion valve characterized by controlling the opening and closing operations of a valve body.
